I don't think Ripley is gay. He appreciates good looks in other men, that's true. But he's married in later books. I'm not saying he's very strong in the sex department. But he makes it in bed with his wife. ↗
It seems like all the good looking people have smaller dogs these days. Especially for the women, because they always come in with their little Chihuahuas and the guys come in with their Golden Retrievers. ↗
